Although The PATH has stood up a CBTC solution to increase capacity and fulfill its PTC requirement as a railroad, they still maintain a reserve system of wayside equipment that follows their historic pattern of signaling and moreover the PATH remains committed to the use of pneumatic point machines and trip stops. The Path Guy captured this newly installed US&S pneumatic trip stop at Journal Square that was supporting a platform extension project. The PATH is likely the last operator to continue to install this type of equipment.
